Definitions

  • This invention relates to safety devices, and more particularly to safety devices for preventing a. movable member such as a traversing table of a v ⁇ machine tool or the like from escaping from its slideways or tracks while moving at high speed in the event of its drive means being accidentally disengaged.
  • a safety stopping device acting by electrical or mechanical braking effect. It can often occur that this safety stop device fails to operate, either because of a failure in :electric power or due to misadjustrnent of the control stops thereof, or for any other reason.
  • the movable member willl then, under the mof fx'nentum built up during its displacement, continue on its movements, and the driven element, such as a rackbar for example, may disengage :and escape from the pinion constituting the driving element. Said movable member can then be shot out of its slideways at high speed and cause accidents.
  • Fig. 2 is a transverse cross-section on line II-II of Fig. 1.
  • the table I of the planer is movable over the slideways II of the planer frame 2.
  • f table I is provided with a stop 3 adapted, in the event the table would overrun its normal traversing stroke, to abut against a part l rigidly secured to a bar 5 of circular cross-section.
  • the bar 5 is formed towards the end thereof opposite from that engaging the part 4, with an enlarged diameter section which merges with the smaller diameter section of the bar through a frusto conical section 8.
  • the bar as shown extends through a ring 6 made of very hard steel acting as a drawing-die.
  • the ring 6 is backed against a support 'I which in turn is backed against a shoulder 9 of a machined section of the frame.
  • said part is supported as shown more clearly in Fig. 2, on two ribs I0 formed on the frame.
  • the above-described device operates as follows: should the table I fail to stop normally at the end of its traversing stroke, its stop 3 will engage the part 4 and carry it with it. The bar or rod 5 is then drawn through the die member 6. The draft force necessary to thus draw the bar through the die produces the desired braking action and brings the movable assembly to a stop.
  • the provision of the frustoconical connecting section insures that the ⁇ braking action is satisfactorily gradual. Another advantage of this frustoconical section is to avert a sudden shock from occurring as the stop 3 engages the part 4.
  • a machine tool of the type including a carriage arranged to reciprocate between two limit positions, a safety device for yieldably arresting said carriage when overrunning one of its limit positions, a safety device for yieldably ara stationarily mounted die member, a drawable bar having a portion fitting through the opening of the die member and a portion wider than said opening, the fitting portion of the bar being extended through the die opening, a first dog fixedly secured to said fitting portion, and a second dog secured to said carriage for movement in unison therewith and engageable with said first dog, engagement of the said dogs forcing the wider bar portion through the die opening thereby vyieldably arresting the carriage, the said dogs being disposed in a relative position in which they are engageable ...for the.,v purpose aforesaid only when the carriageoverruns one of said limit posi'- tions.
